Can anyone tell me why when I record two guitar parts with no changes in amp settings or mic positions and pan them both hard to one side it sounds like shite(single sounds better than double. Double sounds hollow and distant)? If I pan one hard left and then one around 11 o'clock it sounds fine. Is this some kind of phase issue or frequency boosting thing or what? Do you generally want to change mic positions and/or eq settings on the amp when you double? What am I missing here?
